Specification forming part of Letters Patent No. 126,185, dated April 30, 1872.

Specification describing a new and Combined Stove and Water-Heater, invented by CHESTER COMsTOCK, of New Canaan, in the county of Fairfield and State of Connecticut.

Figure l represents a vertical longitudinal section of my improved stove, the line c 0,'Fig. Fig. 2 is a top view, pa-rtly in section, of the same.

Similar'letters of reference indicate corresponding parts.

The invention consists. rst,'in providing the inner sides of the lire-box of a stove with auxiliary and adjustable sides, to lessen the lire-room and the radiation of heat therefrom on the sides; second, in suspending over the oven, between cover and tire-box, and out of range withthe 4holes therein, a water-vessel, which is connected with cold-water vessel on top, and has certain hollow arms and pipes to give a greater heating-surface 5 and, thirdly, in combining these two devices with a waterchamber around the lire-box, all substantially as hereinafter described.

A in the drawing represents the body of a stove of suitable size and kind. B is the fireboX, made with hollow sides and ends to form a continuous water-chamber, a., which is, by pipes b and d, connected with a boiler or other vessel, C. The surplus heat of the fire will serve to heat the water within a, which will circulate within the boiler. The grate D I prefer, in this kind of tire-box, to make in two sections, independently pivoted, as shown in Fig. 2. E E are two vertical slides, which are provided with toothed racks e e, that mesh into pinions ff, as shown. When these pinions are turned, by means of crankhandles g g,

more away from the chamber a. l is a water vessel suspended below the stove-coverGr,

above the fire-box, but so as to clear the holes in the cover G. It has projecting arms h h, which reach back over the oven, and are eonnected by transverse pipesi z', as shown, and is at j divided by a partition to insure completecirculationbefore the colder water comin g from C, through a pipe, l, can return properly heated through a pipe, m. The smoke, passingto the lues over the oven, will give off its surplus heat to the vpipes A partition similar to j, in F, ma-y also be in the water-chamber a, for like purpose.

Having thus described my invention, I claim -as new and desire to secure by Letters Patent- Y l. The vertical slides E E, applied to the sides ofthe Ere-box B, and made adjust-able, substantially as and for the purpose herein shown and described. Y

2. The vessel F, having the arms h h, partition j, and circulating pipes i i', substantially as and for the' purpose herein shown and described. i

3. The combination of the vessel C with the lhollow chamber@ around the lire-box, and with Witnesses:
